2000 Corollas use iridium plugs from the factory. Both Denso and NGK (BKR5EIX I think) are factory spec'd.

From what I read elsewhere when troubleshooting P0420 there's usually more to just replacing the O2 sensor.

Ya, last time I floored my car I got 27MPG, and that's on a 99 without the benefit of VVT-i.
